Template Cell Alignment for Interposer Layout Design

Integrated circuit (“IC”) devices are ubiquitous in the modern world of electronics. However, as designs for IC devices become more complex, planning for placement of components (such as microbump contact pads, chip connection contact pads, and interconnections) becomes more critical. It is with respect to this general technical environment to which aspects of the present disclosure are directed. In addition, although relatively specific problems have been discussed, it should be understood that the examples should not be limited to solving the specific problems identified in the background.

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description section. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter.

The currently disclosed technology, among other things, provides for template cell alignment for interposer layout design. In an example, a computing system receives a first design file for a system on a chip (“SoC”) device from a first device, the first design file including first data indicating initial first locations for placement of a plurality of first sets of microbump contact pads on an underside of a die corresponding to the SoC device. The computing system updates, in a second design file for an interposer device, initial second locations for placement of a plurality of second sets of microbump contact pads on a topside of the interposer device to updated second locations that align with one of the initial first locations or updated first locations when the SoC device is mounted on the interposer device, each of the second sets of microbump contact pads being arranged in a first pattern. The computing system generates information regarding a second pattern for each first set of microbump contact pads that mirrors the first pattern. The computing system updates, in the second design file, initial third locations for placement of a plurality of first chip connection contact pads on an underside of the interposer device to updated third locations, and corresponding locations for a plurality of first sets of interconnections through one or more layers of the interposer device between each second set of microbump contact pads and one of the plurality of first chip connection contact pads, wherein a center of each of the first pattern of each second set of microbump contact pads and a center of a corresponding one of the plurality of first chip connection contact pads are aligned vertically. The computing system sends a design update file to the first device, the design update file including second data, the second data including the updated second locations of the plurality of second sets of microbump contact pads and the information regarding the second pattern for each first set of microbump contact pads that mirrors the first pattern.

The details of one or more aspects are set forth in the accompanying drawings and description below. Other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that the following detailed description is explanatory only and is not restrictive of the invention as claimed.

As briefly discussed above, as designs for IC devices become more complex, planning for placement of components (such as microbump contact pads, chip connection contact pads, and interconnections) becomes more critical. Existing IC device designs require different teams of designers working on different parts of the IC device: (1) an SoC device design team; (2) an interposer design team; (3) a semiconductor package design team; and (4) a place and route team. Each team has its own objectives and concerns, and teams typically work around designs by the other teams, leading to complicated interconnections and differing connection patterns. For example, even if two or more sets of microbump contact pads on the SoC device design are the same on different portions of the SoC device, the overall connections through the interposer and to the semiconductor package for the two or more sets may differ due to the interconnections and the chip connections being at different relative lateral distances from the microbump contact pad locations.

The present technology provides for template cell alignment for interposer layout design. The present technology utilizes object templates and pattern templates (collectively referred to herein as “template cells” or “cells”) within a layout design user interface (“UI”). In some examples, the template cells include vertically aligned pattern templates of cells corresponding to a set of microbump contact pads of an SoC device, a set of microbump contact pads of an interposer, interconnections within the interposer, a chip connect contact pad of the interposer, and a chip connect contact pad of a semiconductor package. In examples, the vertically aligned pattern templates of cells are grouped to itself form a template cell that can be duplicated for design of an IC device or for designs of multiple different IC devices across one or more IC design projects. In this manner, routing complexity is minimized, as is scenic routing (e.g., complicated, meandering routing) within layers of the interposer.

In some aspects, the present technology provides for a repeatable (and identical) correct-by-construction layout of matching custom microbump contact pad macros for both the interposer and a top die. In some cases, the top die can be an SoC chip or other chiplets that are placed on the interposer. The custom microbump contact pad macros on the interposer each has a custom macro (e.g., a matching, corresponding, or sibling macro) placed on the top die. The macros contain the required layout of metal routing layers and vias to properly connect from an underside bump (e.g., a controlled collapse chip connection (“C4”) bump) through the interposer up to the topside microbumps. Microbumps on the top die connect to the microbumps on the interposer. The matching sibling macros on the top die contain the required layout of metal routing layers and vias to properly connect form the microbumps down to other layers in the top die. The custom bumps include different configurations, such as a C4 bump surrounded by and connected to any number of microbumps (e.g., 8, 6, 5, 4, 3, 2, etc.). Whether sued in custom routing or “Place and Route” flows, using these completed custom microbump contact pad macros allows user or the tools to place, in a design file for the interposer, 1000 of such completed N-microbump macros (e.g., 8-microbump, 6-microbump, 5-microbump, 4-microbump, 3-microbump, or 2-microbump macros) instead of separately placing a corresponding 1000 C4 bumps, 1000×N microbumps, 60×N via arrays, and greater than 7×N metal routes, etc., to correctly connect the C4 bumps to the microbumps. For instance, for an 8-microbump pattern, 1000 completed 8-microbump macros are placed instead of having to separately place a corresponding 1000 C4 bumps, 8000 microbumps, 480000 via arrays, and greater than 56000 metal routes, etc., to correctly connect the C4 bumps to the microbumps. When these 1000 completed 8-microbump macros are placed, in the design file of the interposer, at the corresponding locations of the sibling macro placements on the top die, the 8000 microbump placements are guaranteed to be correct. In some cases, rather than the 1000 completed N-microbump macros, 20000 or more completed N-microbump macros may be placed.

As used herein, an LLM refers to a machine learning model that is trained and fine-tuned on a large corpus of media (e.g., text, audio, video, or software code), and that can be accessed and used through an API or a platform. An SLM is similar to an LLM, except that it has fewer parameters and requires less data and time to be trained. An SLM and an LLM each performs a variety of tasks, including generating and classifying media, answering user requests and questions in a conversational manner, and translating text from one language to another.

In operation, computing system(s)may perform methods for implementing template cell alignment for interposer layout design, as described in detail with respect to. For example, example modelas described below with respect toand example template cell alignmentsA-C as described below with respect to, example template cellsof, and methods,,,, andas described below with respect tomay be applied with respect to the operations of systemof.

In some aspects, instead of using each of microbump contact pad as a separate object in the interposer layout design, and having to ad hoc arrange interconnections (including metal stacking, connectivity in the interposer, and connections to the closest C4 contact pad) in a separate and individual manner for each microbump contact pad, the vertical alignment of microbump contact pad pattern cell for the SoC device, the corresponding microbump contact pad pattern cell for the interposer, the C4 contact pad cell for the interposer, the interconnection pattern cells within the interposer, and the C4 contact pad cell for the semiconductor package are grouped as a pattern cell itself (in this case, a vertically aligned pattern cell). The vertically aligned pattern cell can be replicated multiple times across the interposer layout design for the currently designed IC device, or replicated (as a template vertically aligned pattern cell) across IC device designs for a plurality of different IC devices. Multiple patterns of vertically aligned pattern cells (e.g., some with eight microbump contact pad pattern, some with six microbump contact pad pattern, some with four microbump contact pad patterns in various configurations, some with two microbump contact pad patterns in various configurations, or some with single microbump contact pad patterns in various configurations) with aligned C4 contact pad pattern and corresponding interconnections within the interposer may be saved as template vertically aligned pattern cells, and the template vertically aligned pattern cells may be used as desired or as appropriate in different IC device designs. In this manner, consistency, efficiency, reliability, and reduced complexity are achieved. With such template cells being used, once fabricated and assembled, the IC devices have microbump contact pads and C4 contact pads that are “correct by construction.”

In another aspect, custom bump contact pads are created to connect across an interposer layer stack-up (e.g., the vertical alignment interconnections within the multiple layers of the interposer) and serve as contact devices with an SoC die. The custom bump contact pads include one of the following: (A) a single-pin custom bump contact pad(s) that serves as a contact device(s) from a cluster of microbump contact pads to a C4 contact pad and all layers in between and the complimentary SoC die side microbump contact pad pattern cell; (B) a multi-pin custom bump contact pad(s) that allow for unique terminal arrangements at the interposer and serves as a contact device(s) from a cluster of microbump contact pads to a C4 contact pad and all layers in between and the complimentary SoC die side microbump contact pad pattern cell. This instantiation enables “correct by construction” arrangement between layers, while ensuring netlist connectivity across microbump contact pads to C4 contact pads, as well as adhering to requirements of foundries for overlap and alignment of 2.5D and/or 3D designs, while also minimizing routing complexity and minimizing scenic routing at the interposer level. As used herein, 2.5D refers to a packaging technology where active silicon SoC dies are stacked on a passive interposer. As used herein, netlist refers to a description of the connectivity of an electronic circuit, in this case, connectivity between microbump contact pads on the SoC chip through the interposer to the C4 contact pad on the semiconductor package. As used herein, scenic routing refers to meandering (and typically complicated) trace routes in three dimensions through the interposer layer.

As used herein, the terms “topside” (or “top surface”) and “underside” (or “bottom surface”) are used to convey relative directionality for purposes of description of the components and their relative orientations and positions; in actual IC devices in use in real-world environments, the directionality may be flipped, and in some cases (such as where SoC devices are mounted on both sides of the package), directionality of one side is flipped relative to that of the other side. For consistency of description, the semiconductor package is described herein as being below (or down relative to) the SoC die and the interposer. The plurality of microbump contact padscorresponds with, and is formed opposite to, the plurality of microbump contact pads. Likewise, plurality of microbump contact padscorresponds with, and is formed opposite to, the plurality of microbump contact pads. Microbump solder material(also referred to as “microbumps”) is used to join the plurality of microbump contact padsto the plurality of microbump contact padsand to join the plurality of microbump contact padsto the plurality of microbump contact pads, thereby electrically and mechanically joining SoC dieto interposer.

Moreover, while the methods,,,, andmay be implemented by or with (and, in some cases, are described below with respect to) the systems, examples, or embodiments,,A,B,C, andof, respectively (or components thereof), such methods may also be implemented using any suitable hardware (or software) implementation.

As should be appreciated from the foregoing, the present technology provides multiple technical benefits and solutions to technical problems. For instance, designing IC devices generally raises multiple technical problems. For example, one technical problem arises from different design teams for components of the IC device (e.g., an SoC device design team, an interposer design team, a semiconductor package design team, and a place and route team) typically designing placement of contact points (e.g., contact pads) and interconnections based on internal team design requirements, leading to complicated interconnections and differing connection patterns, as discussed above.

The present technology provides for template cell alignment for interposer layout design. The present technology utilizes object template cells within a layout design UI (e.g., for the interposer). In some examples, the template cells include vertically aligned pattern templates of cells corresponding to a set of microbump contact pads of an SoC device, a set of microbump contact pads of an interposer, interconnections within the interposer, a chip connect contact pad of the interposer, and a chip connect contact pad of a semiconductor package. In examples, the vertically aligned pattern templates of cells are grouped to form a template cell of its own that can be duplicated for design of an IC device or for designs of multiple different IC devices across one or more IC design projects. In this manner, routing complexity is minimized, as is scenic routing (e.g., complicated, meandering routing) within layers of the interposer. Further, consistency, efficiency, reliability, and overall reduced complexity are achieved.
